For my generation, Judd posed the same problem as Picasso did for the Abstract Expressionists; you either had to go over, under, around, or through him. Conceptual, process, and Earth Art, each in their own way, constituted a rejection of the ‘speciﬁc object'.
Mel Bochner (2005, p. 70) in: David Raskin. Donald Judd. New Haven: Yale University Press, 2010.
Just as the development of earth art and installation art stemmed from the idea of taking art out of the galleries, the basis of my involvement with public art is a continuation of wall drawings. As soon as one does work on walls, the idea of using the whole wall follows. It means that the art is intimately involved with the architecture. It is available to be seen by everyone. It avoids the preciousness of gallery or museum installations. Also, since art is a vehicle for the transmission of ideas through form, the reproduction of the form only reinforces the concept. It is the idea that is being reproduced. Anyone who understands the work of art owns it. We all own the Mona Lisa.
A sculpture, a map, a photograph; all the forms of my work are equal and complementary. The knowledge of my actions, in whatever form, is the art. My art is the essence of my experience, not a representation of it.

Art happens all the time, everywhere. All we have to do is to keep our minds open.
